Imageability of geo-mining heritage. Case study of Nebida settlement, Geo-mining park Sardinia (Italy)
With respect to the scale of observation and the low-urbanized context, this paper argues perceptual qualities that help the interpretation of heritage settings experienced by walking. Focused on physical environmental indicators and aesthetic qualities to be used in Geo-mining heritage settings, the paper redefined qualities of visual impact from previous findings including geometric features of a path (profile and edges) and imageability as comprehensive perceptual quality. Selected indicators were implemented at two selected routes in the ex-mining settlement of Nebida. Results demonstrated relationships between indicators of path geometry and of imageability; the more complex geometry, the more diverse imageability and experience of walking. Moreover, in the case of Nebida, planned and maintained route offers the less direct and variable experience of Geo-mining heritage than informal track beaten by hikers.
